The formula for the volume of a cylinder is: V=πr^2*h If the volume is 432 cubic inches and the height is 8 inches, solve for the length of the radius. Round answer to 2 decimals.

i already answer this but you can pretty do this problem if you read the question carefully it gives you exactly everything you need.

To solve for the length of the radius, we can rearrange the formula for the volume of a cylinder:

V = πr^2h

In this case, we know that the volume is 432 cubic inches and the height is 8 inches. So we can substitute those values into the equation:

432 = πr^2 * 8

Now, let's isolate the radius term:

432/8 = πr^2

54 = πr^2

To solve for the radius, we need to eliminate the square. We can do this by taking the square root of both sides of the equation:

√(54) = √(πr^2)

The square root of πr^2 is just r, so:

r = √(54/π)

Now, we can calculate the approximate value for the radius by substituting in the value of π (approximately 3.14159):

r ≈ √(54/3.14159) = √17.182766 = 4.15 (rounded to 2 decimal places)

Therefore, the length of the radius is approximately 4.15 inches.
